You know what,
Once, we did do that here. They told us that 24h later it would be okay and no danger for the animals.
I let my cats in the house for like 1 week.
2 weeks later one of my cats were dead in front of my house, on the grass... no external damages.
We Don't know if it was the cause But... I would not take a chance if I were you.
We are never to careful, especially with chimic stuff...
